When John Smedley, president of Sony Online Entertainment, acknowledged the "large scale" attacks on Twitter, he came under fire as well. Knowing that Smedley was on a flight from the Dallas area to San Diego, the hackers made a veiled threat about bombs on his plane.

"We have been receiving reports that @j_smedley's plane #362 from DFW to SAN has explosives on-board, please look into this," the group said to American Airlines on Twitter, pairing that with images of the Sept. 11, 2001 attacks.
